The intervention integrates short, manageable \"snacks\" of moderate-intensity physical activity (2-5 minutes per session, 5-6 sessions per day) into daily routines to accumulate at least 150 minutes of physical activity per week. Participants wear a Garmin activity tracker to objectively monitor physical activity levels. The intervention lasts 12 weeks and includes a 30-minute pre-intervention guidance session, a self-guided manual with illustrated activity templates, and structured follow-up support consisting of one weekly 30-minute in-depth session and two weekly 10-15-minute brief sessions.

Does the Snacktivity™ program improve the cognitive function of participants (including both global cognition and targeted subdomains)?\n2. Does the program improve participants' self-care abilities?\n\nThe study consists of three sequential phases:\n\nPhase 1 (Co-design workshops): Co-design workshops will be conducted with COPD patients, healthcare professionals (nurses, physical therapists, occupational therapists), and family caregivers to culturally adapt the Snacktivity™ program for Hong Kong COPD patients.\n\nPhase 2 (Feasibility Pilot RCT): The adapted program will be tested in a small-scale pilot study to assess its feasibility and short-term clinical effects.\n\nPhase 3 (Full-scale RCT): A full-scale randomised controlled trial will be conducted to evaluate the program's efficacy on the primary and secondary outcomes.\n\nParticipants in the intervention group will be asked to:\n\nParticipate in the culturally adapted Snacktivity™ program that integrates short, manageable \"snacks\" of physical activity into daily routines.\n\nWear an activity tracker to monitor physical activity levels. Complete questionnaires at multiple time points assessing cognitive function, self-care abilities, physical activity levels, self-efficacy, exercise capacity, quality of life, anxiety, and depression.\n\nResearchers will compare the intervention group to an attention control group (receiving usual care with health education) to see if the Snacktivity™ program leads to greater improvements in these outcomes.",[57,58,59,60],"COPD","Physical Activity","Cognition","Self Care",[57,62,63],"cognitive function","self care","NOT_YET_RECRUITING","2026-07-08",{"date":67,"type":68},"2026-07-14","ACTUAL",{"date":70,"type":51},"2026-07-15",{"date":72,"type":51},"2028-06-30",{"name":5,"class":6}]
